Debian packaging utilities for Truecrypt source helps to get Truecrypt running with a minimum of effort under Debian-based Linux systems (Debian and Ubuntu are officially supported). Truecrypt is an open source disk encryption software which uses a concept of containers to store encrypted data. The containers (or volumes) can be read transparently under Linux and Windows. The utilities create installable *.deb packages from the sources and those debs can be used in turn to install the encryption software.
DFF (Digital Forensics Framework) is a simple but powerful tool with a flexible module system which will help you in your digital forensics works, including file recovery due to error or crash, evidence research and analysis, etc. DFF provides a robust architecture and some handy modules.
EncFS is an encrypted pass-through filesystem which runs in userspace on Linux (using the FUSE kernel module). Similar in design to CFS and other pass-through filesystems, all data is encrypted and stored in the underlying filesystem. Unlike loopback filesystems, there is no predetermined or pre-allocated filesystem size.
RawWrite for Windows is a replacement for the DOS-based rawrite, or rawwrite program (the DOS version does not work well under Win95, and does not work at all from NT). This version is designed to work under NT/2K/XP, and 95/98/ME. It has a simple GUI, which makes it easier for first time users to create their Linux boot disks.
Robinhood Policy Engine is a multi-purpose tool for managing the content of large filesystems. It can audit filesystem content, perform accounting, remove old unused files according to admin-defined policies, show customizable alerts based on file properties, backup data to external storage, and more. It has advanced capabilities for Lustre filesystems. It leverages OST usage, and lists or purges files per OST, with policy criteria based on pools and OST index. It can also process MDT changelogs with Lustre v2. Originally developped for HPC, it has been designed to perform all of its tasks in parallel, so it is particularly adapted for running on large filesystems with millions of entries and petabytes of data. But you can nonetheless take advantage of all of its features for managing smaller filesystems.
